Best AI Coding Tools for Go

Our Top Picks for Go

We've tested the leading AI coding tools specifically for Go development. Here's how they rank based on code accuracy, language-specific features, and overall developer experience.

Prompting Playbook for Go

• Specify your Go version (1.21+, 1.22+) to get code using modern features like range-over-func, log/slog, and improved generics
• When asking for concurrent code, explicitly request context.Context propagation, graceful shutdown, and errgroup usage to avoid goroutine leak patterns
• Include your interface definitions when asking AI to generate implementations -- Go's implicit interface satisfaction means the AI needs to see the target contract
• Mention whether you prefer the standard library (net/http, html/template) or popular frameworks (Gin, Echo, Chi) as Go has strong opinions on both approaches
• Ask for table-driven tests explicitly -- AI defaults to sequential test cases unless prompted for Go's idiomatic testing pattern

HTTP middleware with structured logging

A request logging middleware using slog and context propagation, demonstrating idiomatic Go patterns that AI tools generate reliably.

package middleware

import (
	"context"
	"log/slog"
	"net/http"
	"time"
)

type contextKey string
const requestIDKey contextKey = "request_id"

func RequestLogger(logger *slog.Logger) func(http.Handler) http.Handler {
	return func(next http.Handler) http.Handler {
		return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
			start := time.Now()
			rw := &responseWriter{ResponseWriter: w, status: http.StatusOK}

			ctx := context.WithValue(r.Context(), requestIDKey, r.Header.Get("X-Request-ID"))
			next.ServeHTTP(rw, r.WithContext(ctx))

			logger.LogAttrs(ctx, slog.LevelInfo, "request",
				slog.String("method", r.Method),
				slog.String("path", r.URL.Path),
				slog.Int("status", rw.status),
				slog.Duration("duration", time.Since(start)),
			)
		})
	}
